CN102292424A discloses oily flame retardant hydraulic oil composition based on a kind of oleate by trimethylolpropane, should
The wear scar diameter of hydraulic oil is also greater than 0.3mm, failure when FZG test reaches 11 grades, and the oxidation life of rotary bomb oxidation test is low
In 300 minutes.The bearing capacity of above-mentioned fire retardant/anti-flammability hydraulic oil is limited, limits it significantly applied to high-power, high pressure
In liquid Ferrous Metallurgy equipment under mining equiment, ship equipment and hot environment.
Summary of the invention
It is an object of the invention to hydraulic to fire-resistant oily based on the existing class synthetic ester by tricarboxymethyl propane oleate
Oil improves, so that fire resistant hydraulic oil has smaller wear scar diameter, higher FZG failure level.
To achieve the above object, the invention provides the following technical scheme:
